How to disinfect pens? What are the commonly used disinfectants? How to use?

When disinfecting, the floor of the pen, feeding trough, etc. must be thoroughly cleaned first. Before cleaning, spray with clean water or disinfectant to prevent dust and pathogenic microorganisms from flying. Then, clean up the feces, bedding, residual feed and other dirt (the cleaned dirt should be treated according to the feces disinfection method). For pens with cement surfaces, the effect will be better if the dirt is removed and then rinsed with clean water.

The second step is to use chemical disinfectants for spray disinfection. Commonly used disinfectants for preventive disinfection include 10% to 20% lime milk, 10% bleaching powder emulsion, 2% to 4% caustic soda solution, 5% Come to Sol and wait. When disinfecting, start from the distance away from the door, spray the walls, ceiling, floor, feeding troughs, etc. evenly in a certain order; then open the doors and windows for ventilation, and rinse the feeding troughs and drinking troughs with clean water to remove the smell of disinfectants. The dosage of spray disinfectant is generally calculated as 1 liter per square meter. When an infectious disease occurs, immediate disinfection and terminal disinfection should be carried out. Different disinfection drugs should be selected according to the different infectious diseases. Generally, when anthrax and clostridial diseases occur, drugs with strong disinfection effect must be used, such as 10%~ 20% bleaching powder, 10% caustic soda solution and 10% formalin.

Generally, when viral epidemics occur, alkaline disinfectants are often used, such as 2% to 4% hot caustic soda solution, 10% to 20% lime milk, 20% to 30% plant ash water, 5% ~10% bleaching powder emulsion, etc. Commonly used disinfectants and usage methods for pens are shown in Table 8.
